    Lots of hdmi to dvi connectors are coming out lately... and i'm wondering if they actually allow you to see the video in high definition or if they downsaple it somehow... also i have a LCD tv with a VGA in and i was wondering if a converter from hdmi to VGA exist or will ever exist...

    http://www.ramelectronics.net/html/DVI-HDMI_adapters.html

    i consider this quite important to know because i'm satisfied with my tv but since it allows for resolution up to 1368px i would like it to display high definition games (ps3, xbox360...), and none of the consoles will have VGA cables :p

    let me know what you think, and your expereince

    Unprotected HDMI is basically DVI with a different connector, much the same way as DVI allows you to put a standard VGA signal over its analogue pins (only if it's a DVI-A or DVI-I connector though...). Boxes that can turn encrypted HDMI into unprotected DVI do exist but since the keys can be revoked at any time when it's discovered which keys were used they're not a great buy...

    DVI-D and HDMI were made to be backwards compatible. No conversion is taking place.

    Kind of doubtful since HDMI allows for protected content (HDCP). Also this would require an actual "converter" to convert the digital signal into an analog one.

    For posterity, Any time that you see a converter for digital video that is either compact or inexpensive (like the ones on the page you posted), you can usually gather that all it does is change the connector type. Actual conversion/upsampling/downsampling of DV requires some fairly hefty equipment, for example: http://www.nextag.com/hdtv-converter/search-html

    Xbox 360 has a VGA cable (I own one) and it works great. Buy one of those. Not sure if the PS3 will have one.

    my biggest issue is to mod a D-terminal cable from the Wii EDTV set, into a VGA D-sub

    I have it too. the only problem is that it doesnt do PAl50 games (due to sync probably). As such, games like STUBBS dont play,and you re advised to connect a component cable or whatever else.

    Supported resolutions go up to 1338xsomething (or something like that) but I run it at 1280x1024 (1280x720 is also available, and so is 1024x768). <- at this resolution many games are letterboxed (And others arent), and Project Gotham Demo (I dont own the actual game) stretches the image vertically so everything looks squeezed.

    Other than that, it's decent and gets the job done. I ll be honest however, I like 4:3 gaming, and the whole 16:9 thing adds alot of confusion, with some games having borders, other not having, and one stretching the image.

    EDIT: I got it brand new for 7 pounds, including shipping.
